Saved the day!
I had a problem with Mail because of a stupid add on ("unreadmail") that would cause Mail to get stuck, I tried deleting the app but that made Mail unopenable! Using this app I was able to find several associated files (that spotlite couldnt find) and delete them! Take THAT buggy app! Success!! Best $7 Ive spent on my computer!
